suPHP problem after PHP upgrade - ubuntu

[SupuS]

Hi all

Few days ago I installed new version of php on my ubuntu feisty server with suPHP extension. But after sucessfully upgrade I get a lot of php5-cgi segmentation fault errors in /var/log/messages:

Dec  3 14:11:58 s1 kernel: [4978293.463308] php5-cgi[16717]: segfault at 0000000026f2db60 rip 00002ada293b6640 rsp 00007fff83c0aa88 error 4

After that I found index.php files on zencart installations which returns this error. If I go directly to page with this index.php I get apache 500 error. In apache error.log is this line:

Premature end of script headers: index.php

I have a lot of same installations of this application but only some of them returns error. All index.php files are same.

For this time I solved this problem by switching off suPHP extension for problematic webs.

I tried recompile suPHP by using this howto http://www.howtoforge.com/suphp_debian_ispconfig but without success.

Has somebody similar problem or idea how to solve this?

Thanks .. SupuS

Hi,

I started to notice this same issue when I installed new applications in my ubuntu ispconfig server with suPHP.

Until now, everything were Drupals and worked like a charm, but yesterday I saw this issue in a joomla site with mediawiki integration (mediawiki was the culpit) and today the same happens with a brand new eGroupWare.

The only clue I got was "Premature end of script headers: index.php" in the broken applications' sites and I also noticed those "segfault" ugly errors in /var/log/messages as :

PHP Code:

Did you find a fix for this? I full understand why you added the word "urgent" in your post. It's a really frustrating situation been unsure when your service could crash.

The server is a ubuntu-feisty that it's completely up to date... and I installed following "ispconfig-ubutuntu perfect setup" of howtoforge forums and Hans suPHP Debian's howto

Millions of thanks in advance for your help,

Hi

Unfortunately I didn't find sollution. I switched off suPHP feature. Only one relevant thing what I found in suPHP faq is:

Why do my scripts not work and why do I get an "Premature end of script headers" in the error_log?
You probably have installed the CLI version of PHP, but you need the CGI version. Copy the file /build/path/sapi/cgi/php to /where/ever/you/have/installed/bin/php to use the CGI version.

Test it if you can. I don't tried it because I don't think that it is the problem and tests on production server is not so good idea. Everything worked fine before php upgrade so I think that it is some kind of non compatibility between php and suPHP. I would like test and solve this on new server next week. suPHP is wery nice tool for joomla, zencart and some other OS hosting so I need it

Funny. :-)
This is just what I was doing right now, and obviously works.
Good enough until we find a better solution or the issue is magically fixed on next upgrade.
BTW, do you think a dist-upgrade will help on this? I didn't review gutsy packages but it should include newer php versions that probably fix the issue.

> Test it if you can. I don't tried it because I don't think that it is the problem and tests on production server is not so good idea.

Funniest !! :-)

It's exactly my situation.
I have been crossing my fingers while reinstalling suPHP in the production server as I suspect you did.

I will check your suggestion in the testing server as soon as I find time for it, but I'm really curious about the "segmentation fault".

Could it be related with php time or memory limits?

I don't know yet about eGroupWare but Joomla-MamboWiki issue was related with an intensive backtrace function.

Falko: don't you have any comment about this issue?

Keep in touch and thanks a lot for your answer,

m.

I hope for this .. or may be after next php upgrade this error disappear .. because I am sure it came because of php upgrade.

[mbria]

because I am sure it came because of php upgrade.

Me too, but I didn't find any reference anywhere to this segfault related with our php 5.2.1 and suPHP 0.6.2 :-(

Hans had a similar problem last April and with Falko and Till help arrived to the same conclusion: Disable suPHP on the affected sites.

Certainly it all doesn't looks promising.
